The Nutanix Bibleacropolis krplis noun data planestorage, compute and virtualization platform. Architecture. Acropolis is a distributed multi resource manager, orchestration platform and data plane. It is broken down into three main components Distributed Storage Fabric DSF. This is at the core and birth of the Nutanix platform and expands upon the Nutanix Distributed Filesystem NDFS. NDFS has now evolved from a distributed system pooling storage resources into a much larger and capable storage platform. App Mobility Fabric AMF. Hypervisors abstracted the OS from hardware, and the AMF abstracts workloads VMs, Storage, Containers, etc. This will provide the ability to dynamically move the workloads between hypervisors, clouds, as well as provide the ability for Nutanix nodes to change hypervisors. Hypervisor. A multi purpose hypervisor based upon the Cent. OS KVM hypervisor. Building upon the distributed nature of everything Nutanix does, were expanding this into the virtualization and resource management space. Acropolis is a back end service that allows for workload and resource management, provisioning, and operations. Its goal is to abstract the facilitating resource e. This gives workloads the ability to seamlessly move between hypervisors, cloud providers, and platforms. The figure highlights an image illustrating the conceptual nature of Acropolis at various layers Figure 1. High level Acropolis Architecture. Note. Supported Hypervisors for VM Management. F/clip_image010_thumb.jpg' alt='Esxcli Software Sources Profile List' title='Esxcli Software Sources Profile List' />As of 4. AHV and ESXi are the supported hypervisors for VM management, however this may expand in the future. The Volumes API and read only operations are still supported on all. Hyperconverged Platform. For a video explanation you can watch the following video LINKThe Nutanix solution is a converged storage compute solution which leverages local components and creates a distributed platform for virtualization, also known as a virtual computing platform. The solution is a bundled hardware software appliance which houses 2 6. U footprint. Each node runs an industry standard hypervisor ESXi, KVM, Hyper V currently and the Nutanix Controller VM CVM. The Nutanix CVM is what runs the Nutanix software and serves all of the IO operations for the hypervisor and all VMs running on that host. For the Nutanix units running VMware v. Sphere, the SCSI controller, which manages the SSD and HDD devices, is directly passed to the CVM leveraging VM Direct Path Intel VT d. In the case of Hyper V, the storage devices are passed through to the CVM. The following figure provides an example of what a typical node logically looks like Figure 1. Converged Platform. Distributed System. There are three very core structs for distributed systems. Must have no single points of failure SPOF. Must not have any bottlenecks at any scale must be linearly scalable. Must leverage concurrency Map. Reduce. Together, a group of Nutanix nodes forms a distributed system Nutanix cluster responsible for providing the Prism and Acropolis capabilities. Wondershare Free Youtube Downloader Keygen For Mac here. All services and components are distributed across all CVMs in a cluster to provide for high availability and linear performance at scale. The following figure shows an example of how these Nutanix nodes form a Nutanix cluster Figure 1. Nutanix Cluster Distributed System. These techniques are also applied to metadata and data alike. By ensuring metadata and data is distributed across all nodes and all disk devices we can ensure the highest possible performance during normal data ingest and re protection. This enables our Map. Reduce Framework Curator to leverage the full power of the cluster to perform activities concurrently. PatchESXi510201212001. Name Version. Sample activities include that of data re protection, compression, erasure coding, deduplication, etc. The following figure shows how the of work handled by each node drastically decreases as the cluster scales. Figure. Work Distribution Cluster Scale. Key point As the number of nodes in a cluster increases cluster scaling, certain activities actually become more efficient as each node is handling only a fraction of the work. Software Defined. Important. Read the vSphere Migration documentation for guidance about migrating VMware vCenter Server to vCenter Server Appliance. Read the Known Limitations for. How to upgrade ESXi 5. ESXi 6. 0 Update I need to add a correction to this post. VMware now recommends using esxcli software update profile. VMwarevSphere6. 5 ESXi66. The Nutanix Bible A detailed narrative of the Nutanix architecture, how the software and features work and how to leverage it for maximum performance. Esxcli Software Sources Profile List' title='Esxcli Software Sources Profile List' />Command Parameter Command Parameter esxcli. There are three very core structs for software definition systems. Must provide platform mobility hardware, hypervisor. Must not be reliant on any custom hardware. Must enable rapid speed of development features, bug fixes, security patches. Must take advantage of Moores Law. As mentioned above likely numerous times, the Nutanix platform is a software based solution which ships as a bundled software hardware appliance. The controller VM is where the vast majority of the Nutanix software and logic sits and was designed from the beginning to be an extensible and pluggable architecture. A key benefit to being software defined and not relying upon any hardware offloads or constructs is around extensibility. As with any product life cycle, advancements and new features will always be introduced. By not relying on any custom ASICFPGA or hardware capabilities, Nutanix can develop and deploy these new features through a simple software update. This means that the deployment of a new feature e. Esxcli Software Sources Profile List' title='Esxcli Software Sources Profile List' />Nutanix software. This also allows newer generation features to be deployed on legacy hardware models. For example, say youre running a workload running an older version of Nutanix software on a prior generation hardware platform e. The running software version doesnt provide deduplication capabilities which your workload could benefit greatly from. To get these features, you perform a rolling upgrade of the Nutanix software version while the workload is running, and you now have deduplication. Its really that easy. Similar to features, the ability to create new adapters or interfaces into DSF is another key capability. When the product first shipped, it solely supported i. SCSI for IO from the hypervisor, this has now grown to include NFS and SMB. In the future, there is the ability to create new adapters for various workloads and hypervisors HDFS, etc. And again, all of this can be deployed via a software update. This is contrary to most legacy infrastructures, where a hardware upgrade or software purchase is normally required to get the latest and greatest features. With Nutanix, its different. Since all features are deployed in software, they can run on any hardware platform, any hypervisor, and be deployed through simple software upgrades. The following figure shows a logical representation of what this software defined controller framework looks like Figure 1. Software Defined Controller Framework. Cluster Components. For a visual explanation you can watch the following video LINK. The user facing Nutanix product is extremely simple to deploy and use. This is primarily possible through abstraction and a lot of automation integration in the software. The following is a detailed view of the main Nutanix Cluster components dont worry, no need to memorize or know what everything does Figure 1. Nutanix Cluster Components. Cassandra. Key Role Distributed metadata store. Description Cassandra stores and manages all of the cluster metadata in a distributed ring like manner based upon a heavily modified Apache Cassandra. The Paxos algorithm is utilized to enforce strict consistency. This service runs on every node in the cluster. The Cassandra is accessed via an interface called Medusa. Zookeeper. Key Role Cluster configuration manager.
